IN an earlier article in Nature 1 I reported some results of a study of the high-temperature transformation of diamond to graphite. In this work diamond powder of 0–1μ particle size was used.

Diamond is well-known for being the hardest natural material on Earth, though synthetic forms have been developed that are ...

Diamond, graphite and graphene are forms of carbon with different giant covalent structures. Metals and alloys - AQA The structure of metals explains their high melting and boiling points and ...

Physicists have successfully created a lab-grown diamond with a hardness exceeding that of natural diamonds. By subjecting ...

Graphyne is a crystalline form of carbon that is distinct from both diamond and graphite. Unlike diamond, where each atom ...

while graphite is composed of flat layers. The super diamond synthesized by the Chinese researchers has a hexagonal crystal structure, which provides much greater strength. The structure of this ...

Most natural and synthetic diamonds feature a cubic lattice structure but there are rare ... and was created by heating highly compressed graphite. Using this approach, the team made a millimeter ...

saying they successfully synthesized millimetersized lonsdaleite from graphite under extreme heat and pressure. Lonsdaleite, also known as the meteoric diamond, was first discovered in 1967 and is ...

Researchers have described a transformation of graphene in an entirely different form of carbon. The transformation preserves ...
